This looks like a ghost blochchain, until Binance starts to invest into those, the chain is ready to handle big volumes and be fast and cheap, something wich BSC has born to handle ETHEREUM high fees in the past, and many more chains had borned to avoid the huge fees, despite that Ethereum chain still the Liquidity King, and no signs to change such status. There are some projects opening doors into OPBNB but not really using it, unless there are some incentives to make this chain boom it will remain very low demand for it.
